Randomized Experiments

7.1K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Blinding

2.6K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Nature and Nurture

20.7K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Threats to Biodiversity

22.8K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Area of Science:

  • Environmental Psychology
  • Exercise Science
  • Virtual Reality Technology

Background:

  • Green exercise, or physical activity in nature, offers combined benefits of exercise and nature exposure.
  • Virtual green exercise aims to replicate these benefits for individuals with limited access to natural environments.
  • This study explores the potential of virtual reality (VR) to enhance exercise behavior and well-being.

Purpose of the Study:

  • To investigate the psychophysiological effects of virtual green exercise using 360° video and 3D models.
  • To compare the effectiveness of different virtual reality techniques in promoting exercise engagement and recovery.
  • To assess the feasibility of virtual green exercise for individuals unable to visit natural settings.

Main Methods:

  • Participants engaged in treadmill walking under three conditions: 3D model VR, 360° video VR, and a control (blank wall).
  • Emotional state was manipulated using a sadness-inducing video prior to exercise.
  • Quantitative data (heart rate, blood pressure, perceived exertion) and qualitative data on experience were collected.

Main Results:

  • The 3D model condition reported greater enjoyment compared to the control group.
  • The 360° video condition showed a lower walking speed than the other conditions.
  • No significant differences were observed in physiological measures (heart rate, blood pressure) or perceived exertion across conditions.

Conclusions:

  • 3D model-based virtual green exercise may offer supplementary benefits over traditional indoor exercise.
  • 360° video-based virtual green exercise might lead to reduced physical engagement.
  • Virtual green exercise presents a promising avenue for promoting well-being and exercise adherence, though technology choice impacts outcomes.
